Ingredients
For the Bake
- 2 cans refrigerated crescent roll dough
- 1 pound corned beef, sliced or shredded
- 8 slices Swiss cheese
- 1½ cups sauerkraut, very well drained
- ½ cup Thousand Island dressing
- ¼ teaspoon black pepper
For the Topping
- 1 large egg
- 1 tablespoon water
- 1 teaspoon caraway seeds
- 2 tablespoons melted butter, optional
Instructions
Step 1: Prepare the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9×13-inch baking dish.
For easier serving, you can line the bottom with parchment paper, leaving some overhang on the sides.
Step 2: Drain the Sauerkraut
Place the sauerkraut in a fine-mesh strainer.
Press out as much liquid as possible.
For even better results, place it between clean paper towels and gently squeeze out additional moisture.
This step is extremely important because excess liquid can make the crescent crust soggy.
Step 3: Prepare the Bottom Crust
Open the first can of crescent roll dough.
Unroll the dough and press the seams together.
Place it in the bottom of the prepared baking dish, gently pressing or stretching it until the entire bottom is covered.
Step 4: Add the Corned Beef
Spread the corned beef evenly over the crescent dough.
If using sliced corned beef, cut it into smaller pieces first.
Shredded or chopped corned beef works especially well because it makes the finished bake easier to slice and eat.
Step 5: Add the Sauerkraut
Spread the thoroughly drained sauerkraut evenly over the corned beef.
Avoid adding any liquid from the sauerkraut.
Step 6: Add the Swiss Cheese
Arrange the Swiss cheese slices over the sauerkraut.
Slightly overlap the slices so the entire filling is covered.
For an extra-cheesy bake, you can add a little shredded Swiss cheese between the layers.
Step 7: Add the Thousand Island Dressing
Drizzle or spread the Thousand Island dressing evenly over the cheese.
The creamy dressing adds the sweet and tangy flavor that makes a Reuben so distinctive.
Step 8: Add the Top Crust
Unroll the second can of crescent dough.
Press the seams together and carefully place the dough over the filling.
Gently press around the edges to seal the top and bottom layers as much as possible.
Step 9: Add the Egg Wash
In a small bowl, whisk together the egg and water.
Brush the egg wash evenly over the top crescent dough.
Sprinkle the caraway seeds over the surface.
The caraway seeds are optional, but they provide a subtle rye-like flavor that makes the bake taste even more like a traditional Reuben.
Step 10: Bake
Place the baking dish in the preheated oven.
Bake for approximately 25–35 minutes, or until the crescent dough is puffed and deeply golden brown.
If the top begins browning too quickly, loosely cover it with aluminum foil for the remainder of the baking time.
Step 11: Rest and Serve
Remove the bake from the oven.
Allow it to rest for approximately 10 minutes before slicing.
This gives the melted cheese and filling time to settle.
Cut into squares and serve warm with extra Thousand Island dressing for dipping.
Tips for the Best Crescent Roll Reuben Bake
Drain the sauerkraut extremely well
This is the most important tip. Too much moisture can prevent the crescent dough from becoming crisp and golden.
Don’t overfill
Adding too much meat, cheese, or dressing can make the center difficult to cook through.
Seal the dough
Press the edges together as much as possible to help contain the filling.
Use thinly sliced corned beef
Thin slices distribute more evenly throughout the casserole.
Let it rest before slicing
Cutting immediately can cause the hot filling and melted cheese to spill out.
Delicious Variations
Pastrami Reuben Bake
Replace the corned beef with sliced pastrami for a smokier, pepperier flavor.
Extra-Cheesy Reuben
Add shredded Swiss cheese between the layers for an even cheesier filling.
Spicy Reuben Bake
Add sliced jalapeños or a few dashes of hot sauce to the Thousand Island dressing.
Turkey Reuben Bake
Replace the corned beef with sliced turkey for a lighter variation inspired by a Rachel sandwich.
Gruyère Reuben Bake
Use Gruyère instead of Swiss cheese for a richer, nuttier flavor.
Homemade Reuben Dressing
If you don’t have Thousand Island dressing, combine mayonnaise with ketchup, pickle relish, a little mustard, and finely chopped pickles.
What to Serve With It
This rich and hearty bake pairs wonderfully with:
- Green salad
- Coleslaw
- Pickle spears
- Potato salad
- Roasted vegetables
- Tomato soup
- Crispy potato wedges
- Extra Thousand Island dressing
For a party, cut the bake into small squares and serve them as appetizers with Thousand Island dressing on the side.
Make-Ahead Instructions
You can prepare the corned beef and drain the sauerkraut earlier in the day.
For the best crescent dough texture, assemble and bake the casserole shortly before serving rather than keeping the assembled dough refrigerated for a long period.
Storage
Allow leftovers to cool before transferring them to an airtight container.
Refrigerate promptly.
For the best texture, reheat individual portions in a 350°F (175°C) oven, toaster oven, or air fryer.
The microwave works for convenience, but the crescent crust will be softer.
Frequently Asked Questions
Can I use leftover corned beef?
Absolutely. Leftover cooked corned beef works beautifully and makes this an excellent post-holiday meal.
Can I use pastrami instead?
Yes. Pastrami gives the bake a smokier, more heavily seasoned flavor.
Can I use shredded Swiss cheese?
Yes. Shredded Swiss melts quickly and distributes evenly throughout the filling.
Can I leave out the caraway seeds?
Yes. They’re optional, although they add a subtle rye-bread flavor.
Why is my crescent dough soggy?
The most likely cause is excess moisture from the sauerkraut or too much dressing. Drain and squeeze the sauerkraut thoroughly and don’t overdo the dressing.
Can I freeze the leftovers?
Yes. Wrap individual portions tightly and freeze in a freezer-safe container. Thaw them in the refrigerator and reheat in the oven for the best results.
